Note that if the matrix you are entering is an augmented matrix, the last column of your matrix will represent the constants after the “equals” sign of your system of equations. Insert the entries of the matrix, pressing the [ENTER] key after each entry. When finished entering all entries, press [2nd] [QUIT].

SOLVING SYSTEMS USING MATRICES—THE LONG WAY AND …
A system of linear equations is said to be consistent iff the rank of the associated augmented matrix is equal to the rank of the associated coefficient matrix (this means that the system of equations has at least one solution). The system of linear equations is inconsistent otherwise. Solution Forms:
